God has a form just like a human being, two hands, two legs, and He Himself comes to show Him. That is Kṛṣṇa. He is not nirākāra. Īśvaraḥ paramaḥ kṛṣṇaḥ sac-cid-ānanda-vigrahaḥ (Bs. 5.1). Vigraha. Vigraha means form. Īśvaraḥ paramaḥ kṛṣṇaḥ sac-cid-ānanda-vigrahaḥ. Avyaktaṁ vyaktim āpannaṁ manyante mām abuddhayaḥ (BG 7.24). That is stated in the Bhagavad-gītā. You know. Avyaktaṁ vyaktim āpannam: "The original is impersonal Brahman. Now He has taken form." This conclusion, who makes? Avyaktaṁ vyaktim āpannaṁ manyante mām abuddhayaḥ: "Those who are less intelligent, whose intelligence is very poor, they consider that ultimately I am nirākāra. I have taken the form." Sākāra-nirākāra.
No. Kṛṣṇa says, sambhavāmy ātma-māyayā (BG 4.6): "I come out of My good will." Yadā yadā hi dharmasya glānir bhavati bhārata, tadātmānaṁ sṛjāmy aham (BG 4.7): "At that time I appear." Therefore Kṛṣṇa says, janma karma me divyaṁ yo jānāti tattvataḥ (BG 4.9). We have to understand Him in truth, not by imagination, not by malinterpretation, but by fact. The fact is being explained by Kṛṣṇa Himself. Why we should go to understand Kṛṣṇa by the commentary of some less intelligent, some poor fund of knowledge? Why we should?
So this Kṛṣṇa consciousness movement means we are presenting the Bhagavad-gītā as it is. That's all. We have no difficulty. We have no difficulty because Kṛṣṇa is accepted as authority, the Supreme Personality of Godhead, by all the ācāryas; not only formerly, like Vyāsadeva, Nārada, Asita, Devala, many, many big, big stalwart . . . Vyāsadeva everyone knows. Vyāsadeva is the original writer of Vedic knowledge, Vedavyāsa. He accepts Kṛṣṇa as the Supreme Personality of Godhead.
